GB Marine Globe Valve

Advantages for Marine Applications

1. Excellent flow control

2. Reliable shut-off

3. High mechanical strength

4. Good resistance to wear and erosion

5. Easy inspection and maintenance

6. Long service life

7. Suitable for seawater, steam, fuel oil, ballast and other marine piping services, subject to the correct body/trim/material selection.

Overview

Performance Parameters:

Performance parameters like size, pressure, and temperature vary by model and material.

1. Size Range: From small-bore (DN6) to large flanged valves (DN300)

2. Pressure Ratings: Available from 0.6 MPa to 16.0 MPa

3. Temperature Range: Can be designed for standard applications, high-temperature steam (up to 550°C), or even low-temperature environments as low as -196°C

Types & Configurations:

GB marine globe valves are available in several configurations to suit different piping layouts
Straight-Through (Type A): The inlet and outlet are aligned, minimizing flow resistance
Angle (Type B): The outlet is at a 90-degree angle to the inlet, used for changing flow direction-
End Connections: Flanged ends, male threaded ends, and female threaded ends are common
